Title (DE) VERFAHREN ZUR HERSTELLUNG VON CYANESSIGSÄUREESTERN
(EN) METHOD FOR THE PRODUCTION OF CYANOACETIC ACID ESTERS
(FR) PROCEDE DE PREPARATION D'ESTERS DE L'ACIDE CYANOACETIQUE
Abstract: front page image
(DE)Cyanessigsäure-C¿1-4?-alkylester werden durch Pyrolyse von 3,3'-Bisisoxazol der Formel (I) in der Gasphase unter vermindertem Druck in Gegenwart eines C¿1-4?-Alkanols oder durch Umsetzung des Pyrolysats mit einem C¿1-4?-Alkanol hergestellt. Die Cyanessigsäure-C¿1-4?-alkylester sind Zwischenprodukte in der Synthese von Cyanacrylaten oder pharmazeutischen Wirkstoffen.
(EN)The invention relates to a method wherein cyanoacetic acid -C¿1-4?-alkyl esters are pyrolyzed to form 3,3'-bisisoxazol of formula (I) in the gas phase at reduced pressure in the presence of a C¿1-4?-alkanol or by reaction of the pyrolysate with a C¿1-4?-alkanol. Said cyanoacetic acid-C¿1-4?-alkyl esters are used as intermediates in the synthesis of cyanoacrylates or pharmaceutically active agents.
(FR)Alkylesters C¿1-4? de l'acide cyanoacétique qui sont préparés par pyrolyse de 3,3'-bisisoxazole de formule (I) en phase gazeuse sous une pression réduite en présence d'un alcanol C¿1-4? ou par mise en réaction du pyrolysat avec un alcanol C¿1-4?. Lesdits alkylesters C¿1-4? de l'acide cyanoacétique sont des produits intermédiaires dans la synthèse de cyanoacrylates ou de principes actifs pharmaceutiques.
